This is NOT a perfect solution. If you normalize a URL using all the methods in this module, there is a high probability that the URL will "stop working". This is merely a helper module for those of you who wants to either normalize a URL using only a few of the safer methods, and/or for those of you who wants to generate a unique "ID" from any given URL.

When writing a web crawler, for example, it's always very costly to check if a URL has been fetched/seen when you have millions or billions of URLs in a sort of database. This module can help you create a unique "ID", which you then can use as a key in a key/value-store; the key is the normalized URL, whereas all the URLs that converts to the normalized URL are part of the value (normally an array or hash);

There's probably possible to improve the performance of this module considerably, but as premature optimization is evil, I'll wait until the functionality and API is stable.

On my MacBook Pro (2.66GHz i7, 8GB RAM) running Perl 5.14.2, I'm able to run the do_all() method on more than 1,100 URLs per second. This is just a number, as the performance depends on the complexity of the URL.
